I decided to check Wii sales in the US, and sure enough, there's a definite "more units per week sold" pattern that emerges, with a few bumps along the way.
US Sales of the Wii Starting 12 January 2008 in 2-Week Jumps
49,113+61,626 = 110,739
115,296+92,794 = 208,090
180,733+47,702 = 228,435
78,975+192,482 = 271,457
77,195+170,313 = 247,508
255,561+92,705 = 348,266
182,891+98,964 = 281,855
186,662+76,608 = 263,270
398,710+129,919 = 528,629
Notes:
* During the weeks of 23 February and 1 March, the pattern was reversed. No apparent catalyst can be found, but sales were higher than normal for this pair of weeks.
* During the weeks of 22 March and 29 March, the pattern was reversed again. Brawl's street release date in the US was 9 March, possibly accounting for the abnormal rise.
* During the week of 5 April, the supply was abnormally larger. No apparent catalyst can be found.
* During the week of 3 May, the supply was abnormally larger, presumed in the gaming community to have been in anticipation of Grand Theft Auto IV. Supply the following week was also higher than usual for a "down" week, possibly indicating another reversal of "off week" in process.
Sky Render - Sanity is for the weak.
